Sets HypervisorEnforcedCodeIntegrity\Enabled = 0. Memory Integrity (HVCI) runs driver code-integrity checks inside a hypervisor, which costs a few percent CPU and can stutter some games/anticheat. Disabling recovers that performance but lowers protection against malicious drivers. Only do this if you understand the trade-off. Reboot required.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
